Combine few query in one graph

Hi All,

Using PB12.5 Classic here.

Would like to know if it is possible to combine few query to display in one graph. If possible, how?

Example, query and sample graph as below:

Query 1 = Total (A+B)

Query 2 = A

Query 3 = B

(Fyi, there is no direct column to get the value above from database)

And they are grouped by Group 1, Group 2 and so on.

Please advise.

Thank you in advance.

Regards,

Yow
